  1. AScope 1
  2. BScope 3

Show answer and explanation

Answer: C. Scope 2

Under the GHG Protocol, direct emissions such as on-site fuel combustion and process gas releases are Scope 1, emissions from generating purchased electricity and heat are Scope 2, and all other indirect emissions across the supply chain are Scope 3. In fabs, which use large amounts of electricity, Scope 2 makes up a large share.

  • A. Scope 1 is the company's direct emissions.
  • B. Scope 3 is the other indirect emissions in the supply chain.
  • C. Correct. It is indirect emissions from purchased electricity and heat.
